URINOMETER J AR.

Application filed July 25, 1927. Serial No. 208,268.

The present invention relates to a urinometer ar. and the objects andadvantages there o't will be apparent from the detailed description asfollows, taken in conjunction with the accon'lpanying drawing.

In the drawing Figure 1 is an elevation of the urinometer jar embodyingthe features of my invention.

Fig. is a vertical section therethrough, and

3 is a. top plan view thereof.

This nrinometer jar consists of a base 5, a cji'linder 6, and a funneltop 7, all formed together integrally preferably of glass. Thelu'fi'l'Oll'l of the cylinder forms intcriorly an apex base which mayserve a sedimentation glass. Two spouts 9 and 10 are formed in thetunnel top, one of which is covered as at ll, and has a small capillaryopening 12, an d the other is an ordinary spout such as is used onbealters and urine jars generally.

The advantages of this ar over many other types of jars now in commonuse are: No "funnot is needed as a filter paper can be folded and placedin the top. and the urine filtered as it is put in the jar for takingspecific gravity. No dropper required for super-laying the urine onnitric acid for the albul'uen or tor making other Contact tests as thefiltered urine can be dropped directly from the eapillary-spout down theside wall of the tube. l l it is desired to rapidly pour the urine outo! the jar, the open spout selected.

Tlho jar can be used as a sedimentation jar; the bottom having thecharacteristic of one :lor this purpose. This jar can be made of: anysize and applied to as small amounts of urine as t commodale theover-flow From the top of the cylinder in case the hydrometer displacesa large amount of urine in the jar.

To illustrate suppose we have a four ounce specimen of urine. Theroutine procedure would be to fold a piece of tour-inch filter paper andplace it in the top of the jar, it boi no convenient to have the edge ofthis filter paper impregnated with litmus or other indicator, showing};the reaction of the urine which moistens it. After the jar is filled tothe neck of the funnel top, the filter paper is removed. and thehydron'ieter is dropped into the jar. lVhen it comes to rest, thespecific gravity is taken.

red because the wide top will ac- A cc. centrifuge tube or other tube isthen partially filled with nitric acid and held in an oblique position,and the filtered urine is poured out of the capillary spout a drop at atime and is allowed to flow down the side wall and form a layer of urineabove the nitric acid, without admixture of the two solutions.

Also, by using this spoon-rough quantitative tests can be made for sugarand other urinary chemicals.

Then the remaining two ounces of urine which have not been filtered, areplaced in the empty jar and sedimentation allowed to occur.

After which the sediment can be picked up and examined microscopically.

This apparatus reduces the glassware necessary for routine urinalysis toa minimum, and can be made durable as any other jar at very littleadditional cost to the ordinary 'ar. e i

The presentembodiment of the invention, is thought, has been disclosedin detail mere- 1y by way of example, since in actual practice', itattains the features of advantage enumerated as desirable in thestatement of the invention and the above description.

It will be apparent that changes in the do tails of construction, and inthe materials, and in the combination and arrangement of parts may heresorted to without departing from the spirit or seope of the inventionas hereina tter churned, or sacrificing any of .its ad vantages.

Havingthus described my invention, What i I claim as'new is 1. In a.manometer Jar of the class described comprising a base. a cylinderrising from the base and having; its upper end flared outwardly to forma funnel, said tunnel being formed with a spout having a cover thereon,said spout being provided with an opening.

2. In a urinometer jar of the class described comprising a base, acylinder rising from the base and having its upper end flared outwardlyto form a funnel, the bottom of the cylinder being formed with an apexto function as a sedimentation glass and the funnel being provided witha pair o't oppositely disposed spouts, one open and the other providedwith a top to form a small opening.

In testimony whereof I afiik my signature.

MAX SHAWEKER.
